LIGHTING FIXTURE.

. Original No. 1,522,732, dated January 13, 1925, Serial No. 522,757, filed December 16, 1921. Application for reissue filed March 28,

To all whom it may concern Be it known that I, \VILFRID LUMLEY, a citizen of the United States, residing at Conneaut, in the county of Ashtab'ula and State of Ohio, have invented certain new and useful Improvements in Lighting Fixtures, of which the following is a specification.

This" invention relates to a lamp fixture, and has for its chief object to provide a fixture of the indirect lighting type which is highly efficient in its light transmitting and diflusingqualities, and is ornamental in appearance. It is the chief characteristic of this fixture that there is associated with the frame or holder and a plurality of lamps, such as incandescent lamps, a plurality of inverted light reflecting members each individual to a lamp.

The present invention embodies certain features of construction and arrangement which improve the effectiveness and utility of the lanip fixture and the invention may be briefly summarized as consisting in certain novel details of construction, and combina- .tions and arrangements of parts which will be described in the specification and pointed out in the appended claims.

In the accompanying sheets of drawings wherein I have shown two embodiments of the invention, Fig. 1 is a View looking toward the bottom of the fixture as the same is viewed from beneath, which fixture is adapted to be supported from the ceiling, part of a lower central globe of the fixture being broken away; Fig. 2 is a sectional view substantially along the line 2-2 of Fig. 1; Fig. 3 is a top plan View of the fixture of Figs. 1 and 2 with part of the indirect lighting globes and lamps removed; Fig. 4: is a perspective view of this fixture on a reduced scale illustrating the manner in which it may be supported from above; Fig. dis a top plan view and Fig. dis a bottom view showing a modification; Fig.7 is a sectional View on an enlarged scale substantially along the line 7-7 of Fig. 5; and Fig. 8 is a top plan fragmentary'view of the central part ofthe fixture of Figs. 5, 6 and 7. I

Referring now to the form of the invention shown in Figs. 1 to 4, it will be observed that the fixture includes a frame 10,

1925. Serial No. 19,181.

preferably but not necessarily formed of metal, and provided with outstanding arms 10", most clearly illustrated in Fig. 3. Sup ported by and between these arms are the indirect lighting globes 11, preferably formed of translucent glass and ornamented in any suitable manner. These globes which are bowl-shaped and face upwardly, enclose or partially surround lamps 12 which project outwardly from the central'part of the frame through reduced neck portions 11" of the globes. Y

One of the improvements of the present invention consists in the provision of What may be termed a direct lighting lamp and globe at the center of the fixture. This globe is shown at 13 and is preferably formed of glass of a translucent nature, so as to give a diffused light. This globe partially encloses a lamp 14. The light emitted by this lamp is transmitted through the globe 13 in a direct manner as distinguished from the indirect method of lighting brought about by the lamps 12 and the upwardly facing reflectors 11, which while transmitting in a direct manner some of the lightfrom the lamps 12, reflect upwardly the major portion thereof.

To admit of the use of'the lower central globe l3 and lamp 14-as described, the frame is provided with a central opening slightly larger than the neck of the globe 13, and the distributor for the lamps 12 is in the form of an annulus 16 arranged centrally of the fixture and in the form of an upstanding flange. This annulus to which the sock eted portions of the lamps 12 are attached, as best shown in Fig. 2, may be part of the casting of which the frame 10 is formed, or it may be a separate part attached thereto. I have produced very effective results by forming this annulus of spun sheet metal which is set into the central enlarged opening of the frame 10, and is soldered to the latter. In the event the annulus 16 constituting the support or distributor for the lamps 12 is formed of sheet metal, I may, if desired, provide braces such as shown at 17, and consisting of rods which extend from the upper part of the annulus outwardly along the arms 10 and at its ends attach to the arms and annulus by soldering or otherwise. Other suitable bracing means may be Inside the annulus 16 there is fitted a d secured by soldering or otherwise, a-reflector 19, and surrounding this reflector there is a dome 20, the exterior of which may be ornamented to add to the attractiveness of the fixture as a whole. The top of the reflector has an opening through which the lamp 14 extends, and the socket of this lamp is socured to a member 21 attached to the top of the dome by a fastening member 22. As here sho-wnthe parts 21 and 22 are screwed together and. clamp between them the top of the dome 20. The top member 22 has an opening extending down through it to ac commodate the electric conductors 23 by which current is supplied to the central lamp l4 and to the radially disposed lamps 12, the current supplying conductors extending to the lamps 12 being located between the reflector 19 and the dome 20, and therefore concealed from view. Preferably the top of the dome 20'is perforated as shown at 24', to provide for the escape of heat generated by the lamp 14.

The fixture shown in Figs. 1 to 4 has five of the indirect lighting globes 11, and consequently five of the lamps 12, the rays from which are transmitted and reflected, by the globes 11, whereas the fixture shown in Figs. 5 to Shassimplythree of the globes 11 which partially surround lamps 12 whose sockets are supported from a much smaller distributor shown at: 25, and supported by the central part of the metal frame, here designated 26, and having as before, outstanding arms 26 on the adjacent marginal portions of which the globes or reflectors 11 are supported. v

The fixture shown inFigs. 5 to S is not provided with the lower central globe 13, and therefore the central part of the frame is substantially solid instead of being pro.- vided with the fairly large central, opening to accommodate the globe 13 of Figs. 1 to 4. It will be observedthat in this instance the distributor 25 is secured to the central part of the frame 26 by a nut 27 screwed onto a threaded shank at the bottom of the dis tributor. This nut 27 forms in effect the lower central part of the frame 26, and is preferably ornamented to conform therewith. Preferably the distributor 25 is definitely positioned so that the lamps 12 will extend out centrally between the arms 26 of the frame, and in this instance this is brought about by providing at the lower part of the body of the distributor 25, forks or bifurcations 25 which engage upstanding pins 27 on the frame 26,. (see Figs. 7 and 8) v' If desired, all the lamps 12 of either of the fixtures herein shown may be controlled by a wall switch,'or if desired, the lamps may be controlled individually by switches embodied in the lamps and operated by pull chains 28, which as shown in Fig. 7 may be extended through small openings 29 in the lower part of the frame 26.

In addition to the novel features above explained, which are more or less individual to the two lamp fixtures shown in Figs. 1 to 4 and 5 to 8,'respective1y, both these lamp fixtures have common features which are One of these features resides in the novel. means for centering the llldll'flct hghtmg globes 11 between the arms of the frame.

This consists of a series of integral pins or lugs 30shown in. Figs. 2 and 3v and in Figs. 5 and 7 These pins project upwardly from and are carried by the arms 10? and 26 of the frames 10 and 26 respectively, near the margins of the arms. They are so located that they engage the marginal flanges of the reflectors 11, and thus hold the latter in place. On the other hand,.they do not interfere with the removal of. thereflectors inasmuch as it is only necessary to lift the marginal portions of the reflectors above the pins and then move the reflectors radially outward from between the arms.

The second feature common to both fixtures herein illustrated,resides in the means by which the reflectors are supported, For the support of the fixtures, the frame 10 intone instance (Figs. 1 to 4;) and the frame 26 in the other instance (Figs. 5 to. 8) are provided with upstanding lugs or posts 31 which are carried by and project upwardly from the inner portions of the arms 10* or 26*, the posts being on opposite sides of the center lines of the arms. To the upper ends of each pair of posts 31, a cross strap 32 is secured by fastening devices such as screws 33. These are clearly shown in Figs. 2, 3, 5 and 7.

The center portions of the straps are preferably bowed'upwardly, and tothese center portions the fixture supporting devices 33 (see Figs. L and 7) are hooked or. otherwise connected.

It will thus be seen that I have provided certain important improvements in lamp fixtures and while I have shown sumply two forms of the invention, I do not desire to be confined to the precise details shown, but aim to cover all modifications which do not involve a. departure from the spirit and scope of my invention as set forth in the appended claims.
